RealDOOM: Doom Ported to 16-bit Real Mode
(github.com/sqpat)
RealDOOM is an in progress port of the DOS version of DOOM (based on PCDOOMv2) to Real Mode to support 16-bit processors (namely the 8088 and 286). It is meant to be accurate to the original game and id software WADs first and foremost. So it should work with timedemos, and have the support for the same level of graphical detail as the original game.

B800 Text
(shikadi.net)
B800 Text is a text-mode screen dump, and under x86 real mode (such as used by DOS) can be copied byte for byte into video memory starting at B800:0000, causing the data to appear on the screen when the video card is in text mode.

Revisiting the DOS Memory Models
(blogsystem5.substack.com)
At the beginning of the year, I wrote a bunch of articles on the various tricks DOS played to overcome the tight memory limits of x86’s real mode. There was one question that came up and remained unanswered: what were the various “models” that the compilers of the day offered?
